Isaiah 10:22

If it is of these the predestinated remnant, about whom another prophet has said, "The remnant shall be saved;" whence the apostle also says, "Even so then at this time also the remnant according to the election of grace is saved;" assuredly he believes in Christ; just as in the time of the apostle very many of that nation believed; nor are there now wanting those, although very few, who yet believe.

The Jews who slew Him, and would not believe in Him, because it behoved Him to die and rise again, were yet more miserably wasted by the Romans, and utterly rooted out from their kingdom, where aliens had already ruled over them, and were dispersed through the lands (so that indeed there is no place where they are not), and are thus by their own Scriptures a testimony to us that we have not forged the prophecies about Christ. And very many of them, considering this, even before His passion, but chiefly after His resurrection, believed on Him, of whom it was predicted, "Though the number of the children of Israel be as the sand of the sea, the remnant shall be saved."
